The highway tunnel is a high-risk area for fires. Due to the tunnel being a closed and narrow space with high traffic volume and poor ventilation conditions, vehicle traffic accidents are prone to cause fires and spread quickly, posing a significant threat to the safety of vehicles, personnel, and equipment, resulting in huge casualties and property losses.

If the temperature inside the tunnel can be monitored in real time, an alarm can be given in a timely manner in case of a fire, and the highway management office can be notified to take effective measures to immediately implement traffic control, prevent vehicles from continuing to enter the tunnel, and evacuate vehicles that have entered or around the tunnel entrance in a timely manner. It can reduce the greater harm caused by fires and create space conditions and precious time for firefighters to extinguish them in a timely manner.

Itu, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tech Co., Ltd. monitors the internal temperature of the tunnel in real time and provides fire warning and alarm, which is crucial for tunnel fire monitoring.

 

Characteristics of fiber optic temperature control system for highways

1. Ketepatan pengukuran suhu tinggi dan tindak balas pantas.

Resolusi suhu hos pengukuran suhu ialah 0.1 °C, dan ketepatan pengukuran suhu adalah ± 1 °C. The temperature detection time for each channel is about 5 Saat.

2. Pemantauan dalam talian masa nyata.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Jam, and regularly save temperature measurement data to provide auxiliary data for health monitoring of highway tunnels.

3. Distributed detection without monitoring blind spots.

Real time monitoring can be carried out at every point within the range of temperature measurement optical cables, eliminating blind spots in monitoring and theoretically avoiding the possibility of missed fire reports.

4. Flexible zoning alarm control.

Through the monitoring software of the upper computer, Bahagian pengukuran suhu yang berbeza boleh dibahagikan dan diuruskan mengikut keperluan pelanggan. Secara amnya, every 100M optical cable is set as a partition. Tetapkan parameter penggera yang berbeza untuk setiap partition, seperti amaran suhu, Amaran kenaikan suhu, penggera suhu, dan penggera kenaikan suhu, untuk membezakan dengan tepat antara kebakaran sebenar dan palsu, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Dalam sistem ini, semasa mengesan suhu setiap kabel optik pengukur suhu, Ia juga boleh mengesan status kerja setiap kabel optik pengukur suhu dalam masa nyata, seperti kerugian tambahan yang disebabkan oleh kerosakan kabel atau lenturan, dan tepat mengesan lokasi kerosakan atau lenturan. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
